IUD removal

I just recently removed my iud on the 4th day of my period. We decided we are ready to start ttc so I figured I would be able to catch my fertility window just in time for this month. The day after my iud was removed the gates of hell opened and I am nauseous and have heavy bleeding and blood clots that are very abnormal that’s been for 3 days now which brings my period to lasting a week when it usually ends within the 5th day. Is there a reason for this heavy bleeding?
